We have an SAP BW system (NW 7.0) , a portal system (EP7.0) and an ECC system (based on EHP3 for ERP) in our landscape. I want to install the EHP1 for Netweaver for the BW system. How do I go about this? Should I also install NW EHP1 on the portal system also since the BI reporting is done using the portal? If so, will it affect my other applications in portal (ESS, MSS etc).
Please let me know how to proceed.
